Coralville Reservoir Stocking

Stocking involves producing fish fry or fingerlings and releasing them into our lakes or river systems. Fish are stocked to re-establish formerly self-sustaining populations, to provide research data on the effectiveness of stocking and other related practices, and to expand recreational opportunities for Iowa's anglers.

The information below is stocking that was done by the Iowa DNR and does not include stocking that was done by outside parties.
